So I've got Ubuntu MATE 20.04 LTS installed on an old MacBook Air. I can use the screenshot tool, but would prefer to use something like printscreen to take one instantly.
Thing is, Mac doesn't really use a printscreen key. I know that under Windows, the F14 key can be used, but this MBAir doesn't have one of those, either.
I'm thinking of mapping screenshots to F3, if I can. Is there a way to do that?
